LASSA2TRetrieval

An MTEB dataset
Massive Text Embedding Benchmark

Language-Queried Audio Source Separation (LASS) dataset for audio-to-text retrieval. Retrieve text descriptions/captions for audio clips using natural language queries.The original dataset is based on the AudioCaps dataset.The source audio has been synthesized by mixing two audio with their labelled snr ratio as indicated in the dataset.

How to evaluate on this task

You can evaluate an embedding model on this dataset using the following code:

import mteb

task = mteb.get_task("LASSA2TRetrieval")
evaluator = mteb.MTEB([task])

model = mteb.get_model(YOUR_MODEL)
evaluator.run(model)

To learn more about how to run models on mteb task check out the GitHub repository.
